We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
O-rings degrade over time due to heat, pressure, and chemical exposure; replacing a worn or damaged O-ring restores proper system integrity and prevents leaks. This part is manufactured to OEM specifications for direct fit in applicable Caterpillar equipment. Always confirm exact machine compatibility using Caterpillar SIS or the equipment parts manual.
